He was jailed for three years after being found guilty earlier this month.

His actions were completely unacceptable and he has let down his colleagues and the communities he once servedChief Constable Peter Vaughan, South Wales Police

Mr Vaughan said Davies had been in a position of "great trust" which was betrayed by his criminal behaviour.

"His actions were completely unacceptable and he has let down his colleagues and the communities he once served," he said.

"Davies displayed a gross abuse of position and power which will not be tolerated within policing.

He added that the "thorough and determined investigation" carried out by South Wales Police and managed by the Independent Police Complaints Commission (IPCC) demonstrated the force's determination to tackle such behaviour.

Davies was ordered to be listed on the sex abuse register indefinitely following his trial at Swansea Crown Court.

His trial heard how both of the women he attacked in Merthyr Tydfil in 2010 were domestic abuse victims.

'Vulnerable women'

During sentencing, Judge Paul Thomas told Davies: "The sexual assaults you perpetrated on these women were a gross betrayal of your position as a police officer.

"You took advantage and preyed upon vulnerable women for your own sexual ends.

"You targeted them as you viewed them as women who would obviously not have the confidence to complain or be believed if they did.

Following his conviction, the IPCC said it had investigated the way his line managers had dealt with allegations and two senior detectives were facing gross misconduct hearings.
